<Example>
The clocks can be stopped when only MIN-Amp and Speaker-Amp are operating.
(1) Power Up MIN-Amp and Speaker-Amp: PMBP = PMSPK bits = “0”
→
“1”
(2) Disable the path of “DAC
SPK-Amp”: DACS bit = “0”
Enable the path of “MIN
SPK-Amp”: BEEPS bit = “0”
→
“1”
(3) Exit the power-save-mode of Speaker-Amp: SPPSN bit = “0”
→
“1”
(4) Enter the power-save-mode of Speaker-Amp: SPPSN bit = “1”
→
“0”
(5) Power Down MIN-Amp and Speaker-Amp: PMBP = PMSPK bits = “1”
→
“0”
(6) Disable the path of “MIN
SPK-Amp”: BEEPS bit = “1”
→
“0”
